The company’s shares have fallen 44% this year in the wake of missed quarterly earnings and declining PC sales. In May, the company announced plans to trim its workforce by 27,000.

Last month, it revealed that it had uncovered improper accounting practices at U.K.-based Autonomy, which it purchased for $10 billion in 2011. That followed massive write downs from its 2008 acquisition of Electronic Data Systems. The revelations have led to a class-action shareholder lawsuit that accuses senior management of concealing financial problems from investors.
